In general, security features can be incorporated into different materials and in a wide variety of ways. In addition to special substances that are already integrated into the basic materials (e.g. banknote paper), further security features can also be added in the subsequent production steps. The aim is for some features to be visible to the naked eye or simple aids such as UV lamps, while other features are deliberately to remain secret in order to prevent counterfeiting.
Laser technology can be used to create different security features in banknotes, passports, documents and certificates, admission tickets - but also in pharmaceutical packaging.
The possibilities here range from laser cutting for viewing windows, perforating serial numbers, laser structuring of surface features to marking in special inks using UV or fibre lasers.
Depending on the requirements for the security feature, these features can vary greatly in size and type; the counterfeit protection results, among other things, from the high precision of the laser technology in combination with further processing steps in production.
